What are the (top, bottom, left, right) padding values?
These define ‘buffer zones’ where you do not want quilting. This may include areas you want to leave unquilted for binding, avoidance of seam allowances, border size inconsistencies, or visual appearance. For example, if the border width is 5.0 inches high, and the top and bottom padding are 0.25 inches each, then the image pattern will be 4.5 inches high, centered top to bottom.
